To all whom it may concern:

' Be it known that I, JosEPH LEMBLE, a subject of the Emperor ofGermany, and resident of Sennheim, Alsace, Germany, have invented newand useful Im rovements in' :ElGQtIlC Type-lVriters, of which-thefollowmg 1s a full, clear, and exact specification.

The advantages'of the electric t ewriter are well known.- The power to eect the impressions from the type is not furnished by the hand of theOperator, but is automatically obtained by electrical power on themovement of the keys. The result is. that the keys'can be struck legatoand not staccato, that is to say, more lightly, conveniently and quicklythan hitherto." i The strength of the im -ressions is also independentof the strengt of the blow applied to the keys, so that the impressionsare uniform throughout.

The chief-difliculties in the" electric typewriters with ty 'e-wheel ordrum hitherto V proposed lie in t e manufacture ot the cur-- rentcontacts for the type adjustment of the cylindrical type-carrier, thehammer device for. eiiecting the type impressions, the paper carriagecontrolling mechanism and the final cutting off of the current. It hasnot yet been possible in connection with a series of keys to control allthe contacts necessary for a complete operation in such a manner thatthe are each mechanically closed independent y of the other, that is tosay, independently of one another and of magnet armatures, relays andthe like. This problem is solved by the' ele'ctric typewriter formingthe subject of this invention. To this end a group of key-levers throughthe medium of a common intermediate rocking shaft acts in conjunctionwith one and the'same contact wheel arranged to control a triple contactin I such a manner that on the depression-and 1 release ofany one of thekey-levers the said contact wheel is displaced and directly effects afirst contact for the adjustment of the typecarrier,,a second contactfor the paper carriage controlling mechanism and a third for tile returnof the type-carrier to its initial posi 'on and the locking of the sameand also foigcutting oii the current.

is a horizontal section through the contact wheel device and the tycarrier drive, on the broken line K- L of ig. 11. 14 is a diagrammaticview illustrating the electric circuit and connections- The keyboard ofthe machine is divided into two groups of keys, a left hand group and aright hand group, to both groups of keys there are common the typecarrier, which like a weaving shuttle is movable or slidable in a rightand left, hand direction; the type striking device; and the papercarriage controlling device, while the contact devices and the electrictype-carrier driveare separately provided for each group of keys ofsimplicity, only one group of keys, that is to say, the left hand group,is described.

. The key-levers 1 (Figs. 1 and 2) are loosely pivoted upon the rods 2and each is provided with a projection 3 which extends bars forconackwards beneath the'stirrup 4 of a rocking shaft 5 common to all ofthem; each of the said levers 1 is ositively connected by means of alink 6 wit a bell-crank lever 7 so that when a key is de ressed therocking shaft 5 is turned in the irection of the arrow a: and the lever7 appertaining thereto in the direction of the arrow y (Fig. 2). of thebell-crank levers 7 project through an upper frame-plate 8 whichprotects the inner contact devices, the said arms terminating The freearms 95 In the following description, for the sake opposite a series ofpins 9 which, when the levers 7 are swung out in the direction of thearrow y, are pressed backwards by the said levers in opposition to theaction of springs 10, (Fig. l). The pins 9 serve a double purpose.Firstly, when in their rearmost position, they have to retain thetype-carrier.in such a position that the type corresponding to the keystruck is brought directly in front of a type striking hammer, to whichend the distribution of the keys and the arrangement frame and thepartsmounted-therein.

The type-carrier contains three superposed rows of movable types viz.,an upper row containing types of the smaller alphabet, a middle type rowof the larger alphabet and a lower row of types for other characters. Itis horizontally movable in the direction of its length in a guide-frame,the upper and lower guides or rails 14 of which are of a U-shape, thesaid frame being also rovided with rear bars 15 (Figs. 4 and 5). T eguideframe, 14, 15, for thetype-carrier is arranged so that it can bevertically adjusted on upright pins 17, by means of lateral lugs 16, wereby it is possible to so adjust the typecarrier, the upper row oftypes of which (small alphabet) is usually at the height of the head ofthe type striking hammer, that the middle or lower row of typescan bebrought tothe level of the said'hammer head. This vertical adjustment ofthe type-carrier guiding frame is effected by means of two specialkey-levers 18 and 19 (Fig. 1), of which the lever' 18 is pivoted at thepoint 20 and enables the middle row of large alphabet types to move toan extentjcorresponding to the "ratio of its length of arms, while thekeylever 19 is'pivoted at 21 and allows the bottom row oftypes to moveto an extent corresponding to the much longer rear arm of the lever; thestroke of these key-levers is advantageously limited by means ofadjustable stops 22 shown in Figs. 1 and 2. It

will be seen from these figures that the rear.

type-carrier frame to the ,appropriate position to bring the middle andlower rows of type into place. The type-carrier frame extendssubstantially the whole width of the machine as shown in Fig. 1, and thebars 17 which serve as guides for the type-carrier frame are arranged ateach side of the machine. Fig. 2 illustrates the type-carrier in itslowermost position. Upon depression of the lever 18, the frame 14 willbe elevated about one-third of its height, while on depression of thelever 19 it will be elevated to its uppermostposition.

spring 26 which tends to retainthe type in the position indicated. 'hena type rod 25 is struck by the hammer, the corresponding type is pushedout from the rear of the car rier guiding frame against the act-ion ofthe spring'26, recesses 27 (Fig. 6) being provided on the flangeportions of the rails 1 1 and bars 15 for the free passage of the typeplate 24 so that the rearwardly projected type by means of an ink stripor band 28 (Fig. 1) passing at the back of the carrier guiding frame,effects the impression upon the-paper of the aper carriage. In orderthat the types shall not rock about their rod, each of the type plates24 is provided with .a guide pin 29 which is parallel to the rod 25 andinsures its rectilinear movement in the type-carrier. The types can onlybe projected backwards from the carrier-frame in the position in whichthey are opposite the striking hammer and this through the medium of therecesses 27, while at other points of the carrier guiding frame they areprevented by their plates 24 from moving over the flange parts of therails 14 and over the bars 15. The type-carrier is advantageouslymounted on rollers in the guide frame to insure its easier movement.

The .type striking device consists of a hammer 3.1 (Fig. 2) pivotallymounted at the point. 30 and an electromagnet 32 arranged beneath theframe-plate S, the armature 33 of the said magnet being connected withthe hammer 31. When the electromagnet 32 is energized it attracts thearmature 33 and The operation of the type-carrier in order to bring itto the operative position corres ondmg to the particular key actuated ise ected by means of an electromagnet i frame-plate 8 upon a round rod 35(Figs. 1,

guide-bars 41 and 42' and carries a contact 2, 7 and 8) uponlwhich itcan be longitudinally moved, the said rack being supported at t e rearby a guide roller 60 and having engaging with it a toothed sector 37.The rack 36 is'detach'ably coupled at each of its ends by means of afinger- 38 with the stirrup 39.0f a slide 40 which" is movable upon tworing 43. Bydisplacing the rack. 36 the s -s 'des 40 are'carried with italong their guidebars' in order by means of their contact spring 43 tomake a secure contact with the type-carrier retaining pin 9 whichis'pressed backwards by the operation of a keylever.

The rack 36 also carries at its ends two keep-- ing arms 44 which holdthe type-carrier between them and carry it with them as soon as the rackis displaced. pass through the front open part of the typecarrierguiding frame so that the heig ta(ljustment,of the said frame for thepurpose of changing the row of types in use can be effected withouthindrance on the part of the arms 44. On the other hand the rack 36together with the arms 44 can be rocked forwardly in the direction ofthe arrow 2 (Fig. 7) so as to be withdrawn from the stirrups 39 of theslides 40 so that the type-carrier guiding frame together with the.typecarrier can be removed from the pins 17 without difficulty, forexample for the exchange of a type, thecleaning of the types or for theexamination thereof. 1

The toothed sector 37 which engages with the rack 36 is mounted 'upon anupright shaft 45 (Figs. 1, 2, 3 and 13) which carriesat its lower part acircular disk 46 with two radial notches 47. By means of these notchesthe rotation of the shaft 45 to .the left or to the right'can beeffected by forwardly moving the one or the other of two pins 48respectively on two shafts 49 in order 1 to bring the said pin into thenotch opposite sponds, through the medium of the toothed to it andeffect the rotation of the disk 46. The rotation of the shaft 45 to theleft corresector 37 and the rack 36, to a displacement of thetype-carrierjto the left and this rotation is effected in a mannerhereinafter described by the depression of any one of the left-handgroup, while the rotation of the said shaft 45 to the right and thecorresponding displacement of the type-carrier is the result of theoperation of a key of the right hand group. As the means employed forthis purpose are the same for both groups it will suffice in thefollowing description to describe the means appertaining to the lefthandgroup only. The shaft 49 in connection with this group is connected bymeans of a short arni50 and a link 51 with a lever 53 pivoted at 52 sothat it can move in a hori- These arms 44 zontalplane, the said lever 53being connected by means of an articulation 54 with a swinging lever 57carrying the armatures of two electromagnets 55 and 56. One of theseelectro-ma'gnets, namely that designated 55, serves when energized toswing the shaft 49 outwards by means of the-members 53 and '51 in such amanner that its pin 48 is thrown forwards into the corresponding notch47 of the disk 46 in order to effect by a powerful blow the rotation ofthe shaft 45 to the leftand so to slide the type-carrier also to theleft. When {the excitation of the electromagnet 55 is interrupted theother electromagnet 56 comes into operation and returns the shaft 49together with the parts in connection therewith into its position ofrest in which it is retained by means of a flat spring 58 engaging itsunder part (Figs. 3 and 9).

The type-carrier and the actuating rack 36 are retained in their initialposition or position of rest at the middle of a stroke (Fig. 1)

in order that they may be moved to the left or to the right by means ofthe toothed sector 37according as to whether a key of the lefthand or ofthe right-hand'group is struck.

It will be obvious that this initial position or position of rest of thetype-carrier must be exactly determined in order that it shall not,

'bv reason of its momentum, move beyond its middle position to eitherside, in which event, on the next key being operated, an incorrect typeadjustment would result. To this end the shaft 45 carr ing' the toothedsector 37 is provided at its ower part with a transverse rod 61 (Fig.13) which is provided on each side of the shaft with a flat spring 62and cooperates withtwo vertical spring-operated locking pins 63 in sucha manner that in their raised or uppermost position the springs 62 arein contact with the locking pins 63 and so prevent theshaft 45 fromturning in either direction. The raising of each of the pins 63 iseffected by means of a forked lever 65, loosely mounted upon the pin 64,the said forked lever 65 being provided upon its under-side with aninclined surface 66 (Figs. 2 and 12) and being lifted by a pin 67projecting laterally from the link 51 and which, when the link is movedbackwards to its rearmost position, slides on the said surface 66. Thisbackward movement of the link 51 is effected, asalready described, bythe electromagnet 56 which, when energized, displaces the armature lever57 in such a manner that the link 51 is-withdrawn into its rearmostextreme position.

The paper carriage controlling mechanism does not possess any essentialnovel features. The paper carriage 68 (Fig. 1) which is immediatelybehind ink bands 28 and is subnet 70 which, when energized, releases apawlmature (Fig. 2) and of 'a pin 74 on this latter pawl in order torelease the carriage until it is again. locked by the'pawltooth 75 andon the interruption of the excitation of the electromagnet 70 toenablethe pawl 72 to a ain drop into the next space of t e toothed w eel 731"This mode of controlling the paper carriage is known.

In front of the electromagnet armature 69 there terminates a rod 76(Figs. 1 and 2) which extends from the key-board and is longitudinallymovable and subject to the action of a spring. This rod 76 can be pushedbackwards through the medium of a special key 77 in'order to'mechanically displace the armature '69 and to enable the paper carriageto be controlled as desired without theemployment of the electriccurrent.

The paper upon which the characters are to be impressed runs in theknown manner between controllable rollers and, in the constructiondescribed, permits the writing to be immediately visible.

The electric contact devices form one of the essential features of theinvention. As in the case of the other mechanisms I will here onlydescribe the mechanism in connection with the left-hand group of keys.

In the first place mention must be made of a main contact 80 arrangedupon, and insulated from, the machine frameand the mov' able contactmember of which is in theform of a rotatable cam 81 (Fig; 12) and isconnected by means of the arm 82 and the link 83 with an arm 84 (Figs.12 and 13) which is mounted upon,- and insulated from, the correspondingshaft 49 so that when the latter is rotated by the operation of a keythe current which was cut oil is allowed to enter the machine.

In the second place there is provideda contact wheel 85 pivotallymounted at the point 86 and having three contact arms 87 88 and 89-(Fig. 11), the said wheel being adapted to be turned by means of anarm 91 which engages with a fork 90 of the wheel and is mounted upon thecorresponding rocking shaft 5 actuated by the keylevers. I If,therefore, this rocking shaft be turned by the depression of a key, thecontact wheel 85 is si multaneously' turned. The three contact arms ofthe latter cooperate frlctionally wlth three corresponding contactsprmgs' 92, 93

The return of the contact wheel 85 after its rotation is effected bythe action of a spring 97 (Fig. 13) which engages the arm 91 with theinterposition of an insulator.

To describe the operation of the machine reference is made to thediagram (Fig. 14) in connect-ion with which it is to be distinctlyunderstood that for the purpose of clearness 5 several parts are notshown, while other parts are assumed to be differently constructed fromthe parts shown in the machine illustrated in Figs. 1 to 13. For similarparts, however, the same numerals of reference are employed. It isagainonly the left-hand side of the machine which is taken intoconsideration.

Normally the contact arm 87 of the con- 92, the main contact 80 beinghowever broken. No current therefore flows to the machine. Thetype-carrier is secured in its initial or middle position by the lockingpins 63 which are raised and lie in front of the transverse bar 61 ofthe shaft 45 which actuates the type-carrier. If now any one of thekey-levers 1 of the left-hand group be depressed the followingoperations take place. Firstly, the rocking shaft 5 turns in thedirection of the arrow to (Fig. 9) and by means of'a finger 98 mountedupon it'and of a bell crank lever 99 which engages a short arm 100 onthe shaft 49, the said shaft 49 is turned in the direction of the arrow22 (Figs. 2, 9, 12,13 and 14), whereby the main contact 80 (Fig.

14) is closed by the contact cam 81 and our- The contact Wheel 85 isthen, through the medium of the arm 91 of the'rocking shaft 5, rotatedin the direction of the arrows (Figs. 13 and 14) in order to effeet thefollowin contact makings and breakin 's.

The lever 53 isthrough the medium of the link 51 (Figs. 3 and 13) so turned that thearmature lever "57 which normally lies against the electro-magnet 56(position I of Fig. 14) is moved somewhat towards the electromagnet 55(position 11 of Fig. 14). Then, by the dis lacement of the link 51, itspin 67 will sli e from the cam '-v sea-74a surface 66 of the forkedlever 65 (Fig. .2) in order to permit of the downward movemen oftheleft-hand locking pin 63 and so releasingthe type-carrier drive fordisplacing the said carrier tothe left. Finally the rotation "of theshaft-49 withdraws the finger 96 from the contact spring 93 so that thelatter can 96) are broken.

assumeits position of contact (in Fig. 14 this finger is merely shown inconnection with the contact wheel 85). The rotation of the contact wheel85 in the direction of the-arrow 8 makes contact between the arm 89 andthe springig i, While the contacts on the arms 87 and 88 (for the latterarm notwithstanding the release of the spring 93 from the finger Theresult is that a current flows from the ositive pole through the wire1'01, vover the c osed contact 80 through the connection 102, thecontact 89, 9 1, electromagnet and'through the wire 103 back to the neative pole in connection with the machine rame so that theelectro-magnet 55 is now energized in order to powerfully pull thearmature lever 57 osition III shown in Fig. 14) and; through t 1e mediumof the link 5l and whilestill retaining the closed contact at 80, toturn the shaft 49 in the direction.

The continued movement of the armature lever. 57 under the action of theelectroma net 56 brings it finally from the position I into the initialposition I and during this portion of the movement the complete ,returnto the initial positionof the parts of the machine takes place. The link51 is then osition and the shaft 49 com letely ret-urnec so that the pin48 completel i' leaves the notch 47 in the disk 46 and the spring 93 bymeans of the finger 96 is forced out of its contactposition and finallythe main contact-'SO-is broken and current is cut off (Fig. 13). more,on the complete withdra-w alof the link 51, the pint)? thereof slides onthe cam surface 66 of the forked lever 65 (Fig. 2), in order to raisethe latter and with it the look ing pin 63 and thereby, by'means of thetransverse rod 61, lock the shaft 45 and the type-carrier driving gearuntil the next key is struck. In this manner all theparts havere-assumed the initial position shown in full lines in the drawing. Whenanother key is struck the above described operations are repeated, thatis to say, shortly described, the closure of the main contact 80, theexcitation'of the electromagnet- 55, the. displacement of thetype-carrier, the excitation of the type-impressing electromagnet 32,the interruption of the excitation of the electromagnet 55, the returnof the type-carrier by means of the electromagnet'56 and theinterruption of the excitation of the type impressing electromagnet 32,the putting in circuit of the pi er ca-1 'riage operating electroinagnetT0, the locking of the type-carrier in its initial position by means ofthe locking pins 63 and finally the breaking of the main contact 80.
